Licence conditions for pollution studies and reduction programs

Summary
 
Licence number: 12003
Title: EIP 9 - Water Storage Improvement Program
Start date: 25 May 2016
 
Licence Condition
AGL has proposed a project to improve the water storage facilities at the Rosalind Park Gas Plant (RPGP). The aim of the project will result in an environmental improvement and a reduction in pollution consistent with the objects of the Protection of the Environment Operations Act 1997. Background AGL will replace a number of current water storage tanks with purpose built pre-fabricated above ground double walled tanks manufactured to AS1692 (tanks for flammable and combustible liquids) and AS1940 (storage of flammable and combustible liquids). This will reduce the potential risk of loss of containment of the existing storage facilities. Manual leak detection systems will be a feature of these double walled tanks, enabling AGL to regularly check the integrity of the tanks. Tank levels will be electronically recorded and communicated to the RPGP Operator via the SCADA. Program The current water storage facilities at the RPGP consist of the following:  a)  Oily Water Storage – 65 kL in-ground concrete tank; b)  Clean Produced Water Storage - approximate 5 Mega-Litre (ML) bentonite lined flare pit;  c)  Dirty Produced Water Storage – 75kL above ground ‘frac’ tank; and d)  Bund Water Storage – 15kL in-ground concrete tank.  AGL will replace the abovementioned storage facilities a) – c) with the following: a) Oily Water Storage – 70 kL above ground double walled tank b) Clean Produced Water Storage - 2 x 70kL above ground double walled tank and an additional 4.5kL above ground pump tank c) Dirty Produced Water Storage – 70kL above ground double walled tank The 15kL bund water storage tank will remain in service with an additional internal tank liner installed. The current Oily Water Storage 65kL in-ground concrete tank and 5ML flare pit will be taken out of service and remain in-situ until the RPGP is fully decommissioned in 2023. AGL must continue to manage these facilities to ensure no pollution of waters. Timeframes April/May 2016 – Finalise engineering design, order tanks, clean and line 15KL in-ground tank, plant alterations or tank plumbing and electrical May 2016 – Continue plant alterations for tank plumbing, electrical, communications and civils June 2016 – Receive and install tanks October 2016 – Complete project commissioning COMPLETION DATE: 31 October 2016
